How to Calculate Monthly Gross Income From Year End Pay Stub

by Bill Brown, Demand Media

Your year-end pay stub provides a lot of information. It will have, along with the pay and deduction amount of your final pay period, all the year-to-date information on federal, local and state withholding as well as your pay for that year. Given that, you can calculate what your gross monthly income over the year was. You do this by taking an average across the year. To ensure it's gross income rather than net, you must ignore all of the funds deducted from your check. Even though you do not receive those funds each paycheck, they still count as a portion of your gross income.

Step 1

Find the year-to-date pay on the year end pay stub. It should show gross pay, prior to any withholding, and should be the largest figure on the stub. For instance, you may have received net pay of $42,000 for the year, but your gross pay, prior to FICA or other withholding, will be more.

Step 2

Calculate the number of months worked at your present employer. If you worked all year, the total will be 12. If you began during the year, figure the months as close as you can. If you began in mid-month, use 0.25 for each week you worked in the beginning month. For example, if you began in the last week of June, add 0.25 to the remaining six months of the year to get 6.25.
